- W3029271847 abstract "Objective Construction and identification of wild-type and mutant human o-synuclein (SNCA) gene lentiviral expression vector, and its stable transfection into the rat pheochromocytoma cells.Methods The genes were synthesized with particular primer, amplified by PCR and cloned into the lentiviral vector expression plasmid pGC-FU ( with green fluorescent protein (GFP) gene) to construct a lentiviral vector expression plasmid pGC-FU-SNCA-GFP and pGC-FU-SNCA-GFP. After digestion and sequencing, pGC-FU-SNCA-GFP, pGC-FU-SNCA-GFP plasmid and packaging plasmid pHelper1. 0,pHelper2. 0 were co-transfected into rat pheochromocytoma cells (PC12 cells). A stable transfection was established in the PC12 cells. Results By detecting the level of tagged protein of GFP and the target protein, the pGC-FU-SNCA-GFP and pGC-FU-SNCA-GFP expression in target cells was verified. MTT assay was employed to detect cell apoptosis in lentiviral pGC-FU-SNCA-GFP transfected group, lentiviral pGC-FU-SNCAmu-GFP transfected group ( experimental groups), without virus group ( control group) and empty vector group( total four groups cells). After transfection, at different timepoints ( 1, 2, 3, 4 and 5 d) the proliferation of cells was slowed ( the F value was 4. 534, 196. 285, 411. 829, 1282. 049, 3135. 559, all P ＜0.05). PI single staining was used to examine the cell cycle. The percentages of G1 phase, G2 phase,M phase cells were all statistically significant ( the F value was 885.79, 45.03,207.11 ,all P ＜0. 05). The percentage of G1 phase cells in the four groups cells increased significantly (CON group:59. 10 ±0. 35, NC group:68.24 ±0.60, OE group:71.73 ±0. 11, OE group:74.66 ±0.35). Conclusion This study constructs a foundation for further investigation on the basic function of SNCA and apoptosis related diseases.Key words: alpha-Synuclein; Lentivirus; Transfection; PC12 cells ; Apoptosis" @default.
